Business partner collaboration and buy analysis

ABSTRACT

The present invention provides a method, system and computer program product for implementing an automated inventory replenishment process between a manufacturer and a business partner. In one embodiment of the invention, a method is provided comprising the business partner purchasing and maintaining an inventory of goods from the manufacturer, and the manufacturer providing price protection to the business partner for the purchasing of the goods. This embodiment further comprises managing said inventory by using an automated process that takes into account said price protection for the purchasing of the goods.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention generally relates to automated inventory replenishment, and more specifically, to inventory management practices that consider the effects of price protection on inventory stocking decisions.

2. Background Art

Many Original Equipment Manufacturers (OEMs) sell their products through business partners such as distributors, solution integrators, or resellers. Price protection has become a standard element of contracts between an OEM and its business partners to achieve the right balance between inventory and customer service levels in supply chains with short product life-cycles and rapidly changing prices. Purchase price protection is a common feature that is used to entice customers into buying products and/or services. There are several different types of purchase price protection offered by retailers. One common form of purchase price protection includes insuring the purchase price of the product and/or service for a period of time, such as 30 or 60 days. While price protection is intended to provide business partners with an incentive to stock sufficient inventory, it often leads to overstocking resulting in higher inventory-related costs for business partners and increased price protection expenses and sales incentive costs for the OEM.

The prior art includes methods for inventory management under Vendor-Managed Inventory (VMI) contracts. However, existing VMI practices do not consider the effects of price protection on inventory stocking decisions, e.g., Fry et al. “Coordinating Production and Delivery under a (z,Z) Type VMI contract”, Manufacturing & Service Operations Management, 2005.

A vendor-managed inventory system may be based on a network environment which comprises a vendor system, a buyer system and an external network connecting the two systems. The buyer system includes a buyer server, multiple workstations and manufacturing devices, a plurality of storage locations, and a sensor device. These entities of the buyer system are connected or linked through an internal network. Each storage location stores a small quantity of production material to be consumed by one of the manufacturing devices. The sensor device monitors quantities of materials at the storage locations via the internal network. When a quantity of any material falls below a specified threshold, the sensor device triggers an alert signal. The alert signal is then transferred to the buyer server, and material requirements information is generated and transmitted to the vendor system. Afterward, the required material is delivered to the buyer's premises by the vendor. These systems, however, do not take into account the effects of price protection on inventory stocking decisions.

FIG. 2 illustrates a preferred solution architecture and data flow 200. This architecture comprises Information Integration Services 201, Access Services 202, Business Performance Management (BPM) Services 203, Business Dashboard Services 204, Business Process Choreography Services 205, Business Analytics Services 206, a Performance Warehouse 207, and a Service Information Bus 208. The Performance Warehouse may be, for instance, a DB2 database.

The Service Information Bus 208 is a middleware layer that provides a set of infrastructure services to form the intersection between service requestors and the various service implementations. It embeds the Information Integration Services that comprise data bridges for extracting all relevant transactional data elements from the source systems 209 and store them in the Performance Warehouse.

The Business Dashboard Services 204 provide business visualization and collaboration services for human users to participate in all Business Performance Management related activities to achieve continuous improvement. These services may comprise customized portals to display metrics, alerts, and analytics results on the dashboard. They may also comprise portlets for drill-down views of metrics by sales region, product family, brand, and business partner account.

The BPM Services 203 provides capabilities to define and monitor metrics and generate alerts if performance metrics falls short of established goals. Alert conditions are identified during the analysis and design phase. The threshold values for situation detection are gathered periodically, either via formatted flat files or for direct user inputs via the dashboard.

The Business Process Choreography Services 205 provide decision analysis and tracking of actions taken in response to BPM situations.

The transactional data elements 209 may include inventory, sales out, available-to-sell, open orders, and in transit information. Additional information may be provided about product transitions, sales prices, promotions, product constraints, and open-to-sell inventory. The Performance Warehouse may consume information feeds in formats like EDI, spreadsheets, and batch or real-time XML files.

Analytics and Optimization

Sales out forecasting may be done by predicting “run-rate” demand at the business partner from a statistical forecasting model, and analyzing the entire sales out history of a product to construct a sales out profile. Abnormal events are detected that deviate significantly from the historical profile and the effects of outliers are reduced or removed. Order skew is preferably captured by placing large weights on historical sales in the same week within a quarter.

The optimized “Recommended-Buy” is based on a number of factors. These include optimization, including price protection expenses, inventory carrying costs and customer service. Also, preferably inventory is minimized while achieving a target service level (98% product availability).

FIG. 3 illustrates functional aspects of a Forecasting Engine 302 and a Volatility Analysis 304. The Forecasting Engine monitors sales profile, detects observational outliers, and estimates seasonality and skew and product lifecycle effects. The Volatility Analysis analyzes the “lumpiness” of historical sales out. The results of the Forecasting Engine and the Volatility Analysis are sent to an Inventory Engine 306. This Inventory Engine determines the right supply line that supports the run rate demand and product volatility, and makes a buy recommendation based on the actual supply line.

An embodiment of the invention provides a web-based visibility dashboard that provides real-time visibility to business partner sales out and inventories, dynamic forecasting analytics, and innovative inventory analytics for optimized replenishment decisions. This embodiment also provides proactive buy and sell headlights for business partners based on up-to-date inventory and sales information, and proactive automated alerts on stock-outs, aging inventory and price protection risk. In addition, this embodiment of the invention provides dynamic demand shaping to mitigate demand and supply imbalances, and robust product transition planning based on information about predecessor, successor and similar pattern.

FIG. 4 depicts a computer display screen that may be shown in the implementation of this invention. This screen, referred to as a channel view, includes an area 402 used to select a sales channel, and an area 404 used to select a product. This screen display also includes a table 406 that lists a variety of inventory items. For each of these items, the table provides related data, including a sales out forecast, and a recommended buy or sell quantity. The table also includes a column 410 for displaying buy and sell alerts.

FIG. 5 illustrates a second computer display screen, referred to as a Product Detail View that may be shown in the practice of the present invention. This screen display includes a graph 502 showing a current supply line and a recommended supply line also over a given number of weeks. Also shown at 504 is a table that identifies a number of inventory items. The table, for example, may show the number of an item that have been in inventory for various lengths of time.

Sales Forecasting

FIG. 6 shows information flow of the sales forecasting procedure. Historical sales data 601 are inputted to the forecasting engine for each part number and each supply chain partner. In order to deal with the lack of historical data for parts that were recently launched, product transition data 602 is are inputted into the forecast engine. The product transition data comprises predecessor-successor relationships among parts. The sales history of a predecessor product, together with withdrawal date information of the predecessor and product announcement date information of the successor product allows predicting future sales of the successor product.

An outlier detection and correction procedure 603 is applied to eliminate one-time sales events such as corporate roll-outs or promotional sales from the historical sales data. In a preferred embodiment, robust regression can be used to process historical sales data to detect and correct for such outliers.

Next, the processed historical sales data is fed into two forecasting subprocedures. First, a long-term trending procedure 604 detects repetitive sales patterns where, for example, sales in a given period of a quarter follow a similar qualitative pattern in previous quarters. In order to improve the long-term forecast, data points with large deviations from the moving average or median can be discounted. Also, historical data can be discounted based on recency and seasonality. Discounting can be adjusted through control parameters such as discounting factors that are bootstrapped at the beginning of the forecasting process, and subsequently updated based on historical forecast accuracy. This can be implemented through a feedback loop connecting process steps 608, 607, 606 and 604.

Second, a short-term trending procedure 605 detects recent sales trends based on a selected sales horizon, such as 4-6 weeks. For this purpose, an auto-regressive forecasting model can be applied that extrapolates future sales from the evolution of the most recent sales data. Control parameters, such as time to perceive trends, can be bootstrapped at beginning and continually adjusted during the forecasting process as additional data becomes available.

The integrated forecast 608 combines the long-term trend 604 and short-term trend 605 and produces a point sales forecast for a future time period. At the same time, it produces a confidence interval utilizing results for the robust regression model 603. Historical forecast accuracies 607 can be calculated and used to adjust the control parameters 606 that feed into the forecasting procedures 604 and 605.

The inventory planning model in 609 accepts the output of the integrated forecasting procedure 608 and combines information about the current supply line, cost data and supply partner contract specifications to produce a procurement recommendation.

Inventory Modeling

FIG. 7 illustrates the process flow used by the inventory engine to recommend buy quantities. The historical sales data 701 and replenishment lead time data 702 at a part number and supply chain partner level are used to calculate sales variability 703 over the lead time. This is accomplished using statistical methods that first remove outliers in the historical data that would artificially inflate the variability and then calculate the variability after accounting for short-term trends.

The lead time data 702, sales variability over the lead time 703, price, cost and contracts information 704 (such as historical, current and future prices and costs, price protection contract data, service level targets, inventory holding and back order costs), and an integrated forecast 705 (including a point forecast and a confidence interval) are then fed into the supply line calculation 706. The supply line calculation 706 can be performed, for example, using a serviceability-inventory trade-off model (see for example Zipkin 2000), a cost minimization model that includes price protection cost (see for example U.S. patent application Ser. No. 12/127,412, for “Method for Managing Inventory Under Price Protection”, filed May 27, 2008, the disclosure of which is herein incorporated by reference in its entirety), or an aged inventory minimization model based on the user selection to generate the recommended supply line 707.

The difference between the recommended supply line 707 and the actual supply line 708 is then used to calculate the recommended buy quantity 709 at a part number and business partner level.

Embodiments of the invention have a number of important capabilities and benefits. Strategic capabilities include a single point of standardized reporting for an OEM and its business partners, customized inventory decisions for each part based on statistical forecasting and risk-optimized recommended buy, proactive buy/sell headlights to business partners for each part, and proactive automated alerts on stock-outs, aging inventory and price protection risk for demand shaping or demand conditioning. Additional strategic capabilities are robust product transition planning based on information about predecessor, successor and similar pattern, efficient channel collaboration processes with reduced manual efforts, and optimized manufacturing & channel inventory, and end-to-end supply chain synchronization.

Significant business benefits of the preferred embodiment of the invention include fewer inventories in the channel while maintaining high product availability, reduced strain on manufacturing by smoothing the flow of orders results in better supplier collaboration, and lower inventory carrying costs for business partners. Additional important business benefits are fewer inventory write-offs for business partners, improved cash flow and budgeting for the OEM due to reduced price protection expenses, and more efficient management of collaboration process using analytical inventory decision-making and reduced manual efforts.
